The objectives and scopes of this research were confined into the formalization of strategies and technical procedures for recycling PEMs back to permeable wearing courses. The most relevant boundary conditions were the following: mitigating the drawback of clogging and its related consequences (decay of acoustic and drainagebility performance over the time), preserving traditional (bearing properties, skid resistance) and premium (silentness, drainagebility) performance; recycling high percentages of cold milled RAP‐from‐PEM, investigating on collateral effects in terms of sustainability. An experimental plan was designed and carried out, by specifying materials selection, production, tests on recycled PEMs, basic and advanced tests on surface and hydraulic properties of recycled PEMs, analyses and reports. Functional performance resulted quite promising and the tests carried out are encouraging about the possibility of achieving a satisfactory level of surface performance. Practical applications for rehabilitation interventions are outlined.
